On my x86_64 Solaris 10 box Update Manager and smpatch are no longer able to access public update servers. With Update Manager, a warning box appears on startup with nothing more than a yellow triangle/exclamation point and an OK button. Dropping down to the command line,

smpatch analyze

returns the following error "Failure: Unknown host (getupdates1.sun.com) connecting to https://getupdates1.sun.com/". I'm able to visit public internet sites with a browser so I'm confident the public interface is up and working. Any help troubleshooting this would be appreciated.
